To cllwhom 'it may concern.' x

Beit known that I, ALnXANDnRT. BROWN,

:l citizen ofthe UnitedV States, and resident of Syracuse, lin thecounty of Onondaga and Statel of New York, have-invented certain new anduseful Improvements 1n Type- 4 AVVritin Machines, of which the followingis may be set by direct reference tothe paperl in the machine withoutnecessity for the use of any scales. l

To these and other objects which will a ear hereinafter m inventionconsists in certain features of construction and com.-y

'hinations and arrangements of'parts, all of vwhich will be I. fully setforth herein and particularly pointed out in the claims.

strike 'typewri'ting' machine, only so `much of said machine beingshown, however," as-,is necessary to illustrate my invention. 4 y,

y ln said drawings, Figurel is a front to rear vvertical sectional view'of the typewritf ing machine'having my invention embodied.

therein. Fig. 2 is a front elevation of the same. Fig. 3 is a rearelevation of the same. i

F io'. 4 is a bottom view ofthe same. y

fn all the views parts h'ave been omitted and in some of them partsareshown broken away or in section. l l

My invention is applicable to typewriting machines generally. The mainframe of the machine shown in the drawings comprises side plates 1having cast integral therewith corner posts 2, the posts on each side ofvthel machine' being connected together near their upper ends byanintegral'bar 3. The side plates are connected together at theirtops by atop plate 4 secured tothe upper ends of the posts 2'and at the base ofthe machine the side plates are lconnected by a. back plate 5, a. frontplate (S and a plate 7 through openings in which the stems of theprinting keys project. The'l top plate has for a further Tobject to.provide means whereby the column *sto-ps an openin 8 4throl'igh whichthe type bars stri-ke, sai opening being` closed across theront by across barl 10 cast integral with' the top plate. A At the rear of theopenn 0 '8 the top plate is formed into' a dust shieldy 11 to protectthetype bar bearings from dust and grit falling upon the front face of thelaten. I have hot deemed it necessary to illustrate the type action inthis case, as, so 4far as the present invention is concerned, saidtype'action may be of any suitable construction.

Standards 12 rising from the top plate 4support a stationary carriagerail 13 set at an inclination upward and toward the back of the machineand having in its` opposite edges grooves forming ball races forantifriction balls lat-which cooperate with rails 15 and 16l formingparts of the carriage. Said rails are connected at their ends to endpieces 17 which support the axle or vshaft 18 of the roller4 platen 20.0n the -ends of l said platen axle are mounted theusual iinger Wheels21. The precise manner in which the platen is mounted in the carriage isinlmaterial so far as the present invention is concerned, .but it willbe seen by reference to Fig. 1 that the shaft 18 restsin notches in Inthe accompanying drawings I .havel shown my invention applied to afront' the end pieces 17 of the carriage and by reference to 'Fig 2 itwill be seen that ythe-.shaft is journaled in a platen vframe and'coi-nprlses end bars- 22 connected together beneath the platen-by alongitudinally exlending rod 23. This rod supports a paper apron' y24which at its forward edge carries the 4platen and carriage scale 25.

have not been fully shown for the reason that the -ward and rear endsrespectively in frame )lates 31 and 32 constituting parts of a Theseparts rame secured to and depending from the top plate. The gear Wheel27 is connected 'in any suitable manner with a spring 33 mounted in -aspring drum 34 concentric .'with the shaft 30 and this spring and geardrive the carriage toward the left. The motion of said carriage iscontrolled by the gear wheel 28 which meshes with a pinion 35 rotatablymounted on a shaft 36 journaled at its ends in the frame plates 31 and32.4 The rear face of the pinion 35 'is formed rotate with said shaftbya tooth 38 that` with ratchet clutch teeth as shown in Fig. 1, saidclutch teeth normally meshing with corresponding teeth on a sleeve 37slidably mounted on the shaft 36 kbut impelled to plays in acorresponding slot in the sleeve 37; Said sleeve 37 is pressed towardthe front of the machine by a spring (not shown) The construction issuch that when said sleeve is in its normal position with its clutchteeth in engagement with the clutch teeth on the pinion 35, thecarriagewillforce the shaft 36 torotate when said carriage moves towardthe left, but saidcarriage may be drawn toward the right withoutrotating the shaft 36, the ratchet clutch teeth yielding when the motionis in this direction. The

'sha escapement may be of any suitable construcesca ement wheel may bemounted on the 36 or` geared to said shaft and the formed as shown inFig. 1 with a peripheral groove into which projects the end of an arm'40 (Figs. 1 and 2) said armprojectiug from orforming part of avertlcally disy posed rocking member 41 pivoted at its uppositions shownin more accessible position for the per and lower ends .in brackets 42projecting toward the front of the machine from the frame plate 32. vSofar as my invention is concerned, however, the carriage may be fed andtherelease be effected by any suitable means. Y

The tabulator vmechanism comprises one or more column stops l43 whichare mounted on and are adjustable longitudinally of a rackor column stopbar 44 which at its ends .is mounted on arms 45 depending fromthe upperrear part of the carriage, so that the bar 44l hangs at about the levelof the top plate. The arms 45 are so mounted on the carriage as to becapable'of swinging Vto the otted .lines in Fig. 1, or still further tothe positions shown in Fig. 2 so as to bring the stop bar or rack 44 toa urpose of adjusting the stops and also in or er to bring said stop barto a position where the sto s can be adjusted with direct reference to te paper in the machine without the necessity for referring to any scale.This may be brought about by any one of a variety of constructions, butI prefer the construction shown in the drawings. As shown, the arms 45are mounted on a rock shaft 46 to which said arms are rigidly securedgbypins 47 passing through the hubs of the arms and through the shaft. Saidshaft 46 passes through the end pieces 17 of the carriage with reedom torotate therein, and the arms` 45, contacting with the inner faces ofsaid end pieces, prevent longitudinal motion of the shaft. Said shaft46arms 45`and bar 44 constitute a swinging frame that normally stands inthe position shown in Fig. 3 and shown in full lines in Fig. 1.` In order to hold the frame' in this position a Hat spring 48 is secured byscrews 50 to the upper carriage rail 15 and said s ring presses upagainst the under side o -t e hub of one of the arms 45. This hub isformed with a nose 51 so'that when the swinging frame is in its normalposition the spring pressing'against this nose tends to hold it innormal position, but by the time the frame has been swung to theposition shown in dotted lines in Fig. 1 the spring either becomesneutral or tends to throw the frame still farther toward the front ofIthe machine. l

The motion of the swinging frame under the impulse of the spring 4 8 islimited by stop lugs52 formed on the arms 45 contactin with the rearface-of the upper carriage rail 15. The rack or stop bar 44 isof theusual construction, that is to say, it is substantially square in crosssection and is formed 'on two opposite sides with a series ot' crosscuts or slots spaced a letter space distance apart and the column stops43' are made of U-shape so as to straddle the bar and so as to beinserted in any desired pair of these opposite slots. In Fig. 3 I haveshown the rear face of the bar graduated with graduations correspondingto the cai'- riage and platen scale 25, but in some instances thesegraduations may be omitted. It will be noted that in the normal positionof the bar the numerals of the scale are invcrted, Vso that sai-dnumerals are in the proper position to be read when the bar is swung tothe position shown in dotted lines in Fig. 1.

The cooperating tabulator stops consist in the present instance of theupper ends ot' a series of upstanding bars 53' having the form shown inFigs. 1 and 3. The upper ends ol these bars come up behind' the topplate iwhere they are guided in suitable slotsI formed in a guide plate54, which plate is horizontally disposed and is secured by screws 55 tothe under side of the rear i'lange of thetop plate. The bars 53 arecurved toward the front of the machine and then downward so as to passin front of the rear frame plate 5. bringinr the lower ends ot' saidbars inside ot' the Jase ot' the machine. Each of said bars has itslower end pivoted at 56 to the rear end of the right-hand branch 57 otone of a series of yoke-shaped frames; each of which comprises besidesthe tion 'attheextreme right, this being the re.

asses? arm or branch 57 a yoke bar 5K8 and a. lefthand branch orl arm`759. These yoke frames are nested asshown yin Fig. 4 and they are all-pivoted on a rod 6lV mounted inears 62 depending from a cross barwhichat itsends is secured by screws v64E tofbrackets 65 projectinginward'from theside plates 1.

In order 'tot space the yoke frames apart the' arms 57 thereof havewashers 66 strung on the rod 61 between the several arms. f One purposeof the yoke frames is tol give wide bearings yfor the arms :E7-which arein eiiect lever` arms. 1 Another purpose of these yoke framesisto""reverse the'order of the kkeys with y'relation toy the denominationstops.

Denominational tabulators as ordinarily constructed'heretofore haveusually had the keyi'corresponding to the decimal point at the extremeleft of the series of keys andthe key corresponding to the highestdenominaverse of lthe order of the digits and decimal point as actuallywritten on the aper. lt is desirable to'make lthe order fo" the keys thereverse to that just recited so as' to bring said keys into the naturalorder in which the numbers arewritten. To this end the keys areconnected with the left hand branches 59 of the yoke frames, thesebranches being larranged in the reverse order to the branches 57 towhich the stops are connected.

The tabulator keys 67 are arranged in or near the keyboard of themachine, being disposed in a-transverse' rowVba/ck ofand a little abovethe rear row of printing keys.

i Said keys 67 have long vkey stems 68,1said cured to the arms 59' byrivets 72.

' operated. e5`

stems, as shownfi'mthe resent instance, being lmade of sheet metag andthekeys consisting of the forwardly bent upper ends of the stems. Eachof the key lstems 68 is piv' oted at`70 to the'forward` end of a leverarm 7l, the rear enti of which -forms part of or is rigidly secured tome of the branches 59 of the nested yoke fr" mes. Asshown in the presentinstance, the'lever arms 71. are se,- 'lhe arms 7l have their forwardvends disposed'in any properly with-thel arms 59. The lever arms 71 hebeneath the yoke frames as shown in Figs. 1 and 4, the rear'end ol eachof 'said arms extending upward 'to the point'whcre' it is connected withthe zii'nfill.v A; sp'ace is thus lett. between theseveral yoke bars .i8

and the several lever arms 71 so, thatwhen any key 1s depressed and itscorresponding` yoke bar 58 is alsodepressed there-is space enoughforkthe downward motion of said yoke bar without strikingthc leverarms-71- com1ected`with those Ikeys that have not been y lt will beperceived that Aeach key is con;

z the correspondin 4andspace the two plates apart.

.that the rear 'end of the arm 57 has a tabulator stop connectedtherewith. Each of'the arms 57 ist'herefore in effect a rearwardlyextending arm of a 'lever of the first order, lever arm 71 being the-forwardlyvextendmg arm of the same lever. The construction is such thatwhen any key 67 is depressed the corresponding stop bar n53 is elevatedvertically into the path of the column stops 43. Itv will also ybeperceived that these levers of the first order are crossed, each onecrossing all of the others so that the rearwardly extending arms'of saidlevers which 'are connected with the stops areal`- ranged in an orderthe reverse of that of the forwardl extending arms which are connectedwit i. the keys.

The -tabulator stops and their connections are restored to andretainedyin normal position bya series of leaf springs 73 which pressdownward on .the upper edges of the arms 57. l As shown in the presentinstance these springs are formed for convenience as fingers Floweredges bent toward the rear of the machine -to form upper andylower-flanges nected with a lever arm 7l which is rigidly f 81` and 82which contact with the plate 76 The key stems come up between the plates78 and 76 and are guided'in suitable notches cnt'` 'in the flanges 81and82, as shown in Fig. 1.

The edges of these notches prevent motion of the key stems toward theright or left and the bottoms of the notches prevent motion of the keystems toward the front -ot the -machine Motion of saidkey stems towalrdthe rear vof the machine is prevented yby a rib 83 struck up from theplate 76 and plate 78'toward the rearv or by -formedeither bybending thelower edge, of 4the -bending the lowenedge of the plate 76 toward" the'front. The guiding devices` fjust" described are preferably arranged tocoperate with the key stems having their `flat sides toward theI frontand rear of the machine, but below said guiding ldevices said key stemslare twisted through y about a quarter turn so as to connect properlywith the lever arms 71.' lt will he .seen v that the denomination stopsand their keys and connections are all built into the machine but all ofthese parts are very readily detachable from the machine. The keys anilA, the key stemsy with the bars 53' may be revmoved by removing thescrews 65 Which seenre the `bei' 68 in pleee- With these t'Wo partefreed 'from vthe framework ,then thie entire part of themeclianism maybe dropped ont ofthe .rneehine from below enfl the guide/Plate 54 may berleinoved, if Ldeslred, by removing the screws 55. 1-here will thnerenieininthe machine none of the tabulato'r mechanism excepty theswinging rack'which is'not ordinarily removed from the machine. Whenthemabulator mechanism is removed from the'm'achine a plain plate ofsheet metal may be, substituted for the plate 7 G, for the sake ofappearance, if

desired. The denominational values of the several-keysare indicated'b'ynumerals or 'other Characters printed orotherwiee iin: pressed on thefront face of the plate '78 as Indicated in Fig. 2 Where it will be seenthat these keys are arranged in their natural order instead of in thereverse order as has been usual heretofore.- l

In order to release the carriage` when any tabulatorrke is depressed, auniversal bar 84 iS Provi ed, Serri' universel ber lying across all ofthe-arms 57 and 59 near -the rear ends thereof. I-prefer'to arran e .the

universal bar across both .the armsli 59 so that said universal bar willbe properly operated in case there should be any yielding in the.voke'frernes when e keyie -depreeeed as `there is more resistanceoffered to the operatien of the universal bar than v Athere-is'to theoperation'of" the tabulator Stopv itself Seid universel ber is eer'rieri.by'srins S5 mounted on einheit 86 the@ .iS Jn'onnted in enreor luge 87Projeoting )from theend pieoe .5 v.ofthe mainframe! @ne of .the irme 85has Proieeling downwelrrily therefrom a lever orne 88 irhieh' iS driedto'coperete ,with n, eroSS nieoe'or Wrist pin 8 0 vprojecting from'alever arm 91 lwhich in turnl projects from a or' short rock ehn-ft 92:pivoted'in eers 93 Proieieting troni the Iframe piece 5'. An arm 94'projecting upward from 'the rockshaft' or hub 92 has its upper endStanding J'nenin front of the arm 40 of the carriage release device. Theconstruction 'is such that `when 'any tabu# lator key is operated theuniversalfbar 84 is raised and the arm 94 is moved toward the .reen ofthe rneehine,l Carrying with it the arm 40 and the' sleeve 37 and movingthe clutch teeth on said sleeve. out of eilgge' ment with theclutchteeth on the pinion 35. thusreleasng the carriage and when saidkey is releasedl the sleeve-37 is pressed toward.

the front yof the machine by its spring, bringing the clutch teeth againinto engage` ment and thus restoring .the C21-Triage to the control of-the escapement. yIt will, of course, be understood that by the samedepression of the key one of the bars 53 is moved vupward ifnto the pathof the column stops ,to arrest the carriage.

The construction of the arts is such as to make it convenient to a justthe column stops A3 by ldirect reference to the paper itself. The mannerin which this may be done is illustrated in Fig. 2whereasheet of paper95 is shown inplace in the machine and having lines 9,6 ruled thereondefinino' columns. The rack 44 is swungv forward towardthe fronty of themachine and the paper thrust beneath vand 4behind it between the arms45. The column stops are'tlien set on theJ rack or bar 44 to corres ondwith thel lines 9.6 asshown in Fig. 2. s here shown one of these lineshappens to come at the sixth letter space vrosltion on Ithe/scale 25,anotherat the fortietll, another at the sixtyrst and another at thesixty-ninth letter ispace position. Another column stop is 'shown in theact of being inserted at thc thirteenth letter space position, althoughthere is no ruled line on the paper at this position. It-Will, ofcourse, be understood that the stops may be set by reference `directlyto the paper whether there be ruled lines or not.

@In Fig. 3 the column stops are swung back tol theiroperative ositionand set as shown in Fig. 2. In this figure it Will-be seen that thecolumn-stop corresponding 'to' letter space position forty has just beenarrested by the denomination stop Acorresponding tothe decimal point,which brings letter-space position fort-y to the printing point, asshownin Fig. 2. The arrangement is such that when any column stop isset asshown in Fig. 21at acertain let` shown ter' space position theytabulator key Aand dei .nomination Stop eorresponding .to the dechimalpoint Will'bringthat letter space position of the peper to the PrintingPointlf will be obvious that ,by movin' .thedenolni nation stops onelway or the 051er any other one lorf said stops might be arranged tobring the point at which the column stop is set to the -printing point.

'In case the tabulator is used yfor writing 'amounts in UnitedStatesmoney, the entire series of denomination stops might be moved two letterspaces toward the right-hand oi the operator, or toward the left as seenin Fig. l3,*With the result that when any tabulator key was depressedand the slun in United States money was written, the units of centswould come to the point on Vthe paper at which the column stop had beenset'. As far as I am aware it is broadly new to pvlOYldc any means forbringing the paper in the machine into such relation with thc tabnlatorstops as to enable the operator to set'said stops by direct'reference tothe paper and wish certain of my claims di rected to this feature to belunderstood as i and arrangement It will be understood, dff course, thatthe;

swinging rack is useful in itself aside from the setting of the stops:directly by vthe paper. `The rack bar 4,4 as shown in the present caseis provided with a' scale corresponding to the platen scale 25 and thebe set by reference to this scale if stops may preferred. Even when thestops are set in this manner the swinging rack feature makes the settingof the' stops a much more convenient opera-tion than it has usually beenheretofore.

I contemplate a construction in which arms similar to the arms 45,support a bar on which are mount-ed the margin and line lock stops.,This' construction is claimed specifically' in another a plicatinof'mine,

tiled June' 10th,'l907, l erial No. 378,271,

but. some ofthe claims of the present case' are intended to be broadenough lto cover said construction. In other words, some of the claimsin the present case are intended to be broad enough to cover not, onlytabulator stop mechanisnnbut also other forms of carriage stopmechanism.

It will be understood that my invention comprises features which are ofuse inde- [lendently-or. in other relations than those here shown, andalso that various changes may be`made inl the details o-f constructionmy invention.
